CHARLES G. CONN, OF ELKHART, INDIANA.

PISTON-VALVE MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 249,012, dated November1, 1881.

Application led April 2, 1881. (Model.)

To all whom t may concern:

Be it known that I, CHARLES G. CONN, a

l citizen lot the United States, residing at Elkstrnments, of which thefollowing is a specitication.-

'lhe object ot' my invention is to produce an instrument with a perfectclear-bore valve and a lighter and better valve-action than instrumentsof ordinary' construction. To this end I construct lny valve with alongitudinal bore, using the bottom ofthe valve-piston for one of thewind-passage apertures; but instead of connecting the adjacentvalve-casini gs by a bend leading from the bottom of one valve to thebottom of the next, as has heretofore been done, lemploy a pipeconnected longitudinally with the bottom ot' one valve-casing anddelivering transversely into the body ot' the next, and a pipe connectedlongitudinally with the bottom ot' the second valve-casing anddelivering transversely into the body ot' the third, as hereinafterdescribed.

In the accompanying drawings, Figure lis a side view of atrombone-a-pston illustrating the invention. Fig. 2 is a verticalsection ot the three valves thereof, the first valve being showndepressed and the other two in their upper or normal position. Fig.3 isa vertical section through the first valve at 3 3, Fig. 1. Fig. 4 is avertical section ot' the second valve at 4 4, Fig. l. Fig. 5 is asideelevation of the central portion of a cornet embodying the invention.Fig. 6 is a side elevation ot a bass-horn embody ing the invention.

The ingress from the mouth-pipe is shown at I, and the egress to thebell at E.

A, B, and C are, respectively, the tirst, second, and third valves, anda b c their respective casings. The ingresspipe I opens into the body orcentral part ot' the casing a, and the egress-pipe E leads from thebottom of the third casing, c.

G H are the direct air pipes or passages communicating from the bottomof the first valvecasing, a, to the body or central part of the secondcasing, b, and from the bottom of the second casing, b, to the center orbody ot' the third casin g, c.

The valves A, B, and C are, respectively, made, as shown, with atransverse air-passage, d, passing directly through from side to side,as in Fig. 3, or in knuckle form in and out on the same side, as shownin Fig. 4, as preferred or as the form of the piping may require, and alongitudinal passage,f, opening below through the bottom or lower endot'the valve and above through a curved port in its side, so as in thenormal or upper position ot' the valves to take the wind, which isdelivered horizontally through the body ot' the casing by the pipe I,Gr, or H, and deliver it downward through the pipe G, H, or E, as thecase may be.

J, K, and L are the valve-bends connected with the respectivevalve-c;\sings for producing the valve-tones when the valves aredepressed, at which time the wind, entering the casing horizontally, asbefore, instead of passing directly downward to the next communieatingpipe, is carried through the passage d to the I'irst end ofthevalve-bends J, K, or L, and after passing through this is delivered tothe lateral opening or port of the longitudinal passagef, to beconducted to the next connecting-pipe G or H or the egress E.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

The combination, with valve-oasings a b c, of the connecting-pipes Grand H, leading from the bottom ot' one valvecasing to the body orcentral part ot the-next, and from the bottom ot` the second to the bodyor center of the third, and the valves A B C, formed with transverse orknuckle and longitudinal passages d f, the latter being arranged tocommunicate at their upper and lower ends with the upper and lower ends,respectively, of the connecting-pipes G and H, all substantially asshown and described.
